Stainless-steel switches offer protection against water, dirt, chemicals, heat, shock, and impact, making them ideal for operating equipment in hazardous environments. The stainless-steel push buttons and indicators come in the popular 22.5- and 30.5-mm sizes. The company can also supply stainless-steel switches with LED illumination for use in poor lighting conditions. The switches can also be laser-engraved with symbols and legends that will not wear off or corrode. Other options include self-cleaning, snap-action switching elements with gold-plated silver contacts. For particularly aggressive environments, certain switches may be specified with silver/palladium contacts.
